[PATCH] Avoid breakpoint query in MI

[Nick Roberts <nickrob@snap.net.nz>]

This updates my earlier patch
(http://sourceware.org/ml/gdb-patches/2008-01/msg00421.html) from the thread
"bug in mi when setting breakpoint" started last year by Dodji Seketeli.  It is
simplified by Joel's recent patch for multiple symbols and Vladimir's concept
of top-level interpreter.

I see the default for multiple-symbols is 'all' (it used to be 'ask', perhaps
this change should be mentioned in NEWS) which might make this change more
acceptable.
